cavity back iron

“Cavity-back” is a golf term that refers to a specific design feature commonly found in golf clubheads, particularly in irons. In a cavity-back design, the back of the clubhead has a hollowed-out cavity or recess, which redistributes the weight around the perimeter of the clubhead.

Here are some key points about cavity-back golf clubs:

  1. Forgiveness: Cavity-back irons are designed to provide forgiveness to golfers. The redistributed weight around the perimeter of the clubhead increases the moment of inertia (MOI), which helps to reduce the twisting or “off-center” shots that result in less accuracy. This forgiveness can benefit golfers who may not consistently strike the ball in the center of the clubface.
  2. Larger Sweet Spot: The hollowed-out cavity in the back of the clubhead allows manufacturers to enlarge the sweet spot—the ideal area on the clubface for maximum distance and accuracy. A larger sweet spot provides more room for error, making it easier to achieve solid contact and improved ball flight.
  3. Lower Center of Gravity (CG): Cavity-back irons generally have a lower and deeper center of gravity compared to other club designs. This lower CG promotes a higher launch angle, helping to get the ball airborne more easily and maximizing carry distance.
  4. Game Improvement: Cavity-back irons are often associated with game improvement or super game improvement clubs, as they are designed to cater to golfers who seek more forgiveness and easier playability. These clubs are commonly used by beginners, high-handicap players, or those who prefer a more forgiving iron design.

It's important to note that while cavity-back irons offer forgiveness and playability advantages, some advanced or skilled players may prefer the feel, workability, and control of other club designs, such as muscle-back or blade irons. Golfers often choose their clubs based on their skill level, swing characteristics, and personal preferences.

If you're considering purchasing golf clubs, including cavity-back irons, it's recommended to visit a reputable golf retailer or consult with a golf professional who can help you select the best clubs for your game and provide a club fitting to ensure the proper specifications for your swing.

These clubs get their name from the hollowed-out space on the back of the clubhead. This cavity is formed when most of the club’s weight is distributed around the perimeter. (The term “cavity-back” is synonymous with “perimeter-weighted.”)

Cavity-back irons feature a larger effective hitting area and sweet spot than traditional, blade-style irons, and produce longer, straighter results on poorly struck shots. This makes cavity backs a popular choice among mid- to high-handicap golfers. Perimeter weighting also creates a “gear effect” which causes off-center hits to curve back toward the target.

Many, but not all, cavity-back irons have larger heads than blades. Thomas Golf ( offers a variety of cavity-back iron sets.
